I love making apex cables for them reef central has kept me busy.

Looks really well done ! If you still have pump vibrations making noise, silicon tubing will really kill it substantially vs braided poly. You may be fine, just something to consider. Good luck !

I dunno, I kinda like the idea of getting your new tank setup completely, match parameters to your old tank, then set up the drain to temporarily shunt from the new tank to the old sump with a very small pump returning water to the new tank. You could kind of follow the mold of richard's FragZoneTM

Whats the risk with the new rock as far as linking tanks? Seems to me that the parameters that matter wrt to RTN/STN (alk, temp, salinity) aren't going to be affected by the inclusion of new rock. Pests i guess? But those would be there eventually waiting for the new coral anyway.

Talked to hunter at AD, he gets in ORA once monthly (and already sold last months alottment. $20 bucks and they come in golf ball clumps. I told him to order several for us ARC'ers .

I'm down for some.

ORA distributors (aquadome is the only one i know offhand).

This'll be the first macro that I want in my DT. "Blue Hypnea (Hypnea pannosa) is an iridescent blue ornamental algae. Though similar in appearance to Ochtodes sp. algae from the Caribbean, this species originates from Micronesia and has slightly different morphology. Blue Hypnea grows in very dense, matted clumps that loosely anchor to coarse substrates. It is not a particularly fast growing algae so containing its growth is not difficult. We recommend moderate to high, full spectrum lighting for optimum coloration and growth. Photo taken under 10k Metal halide with supplemental flash."

OR get a DC return pump. JUST. SAYIN.

It's not terribly unusual to see tanks run bare bottom. You lose out on the biological filtration capacity of the sand, and the space for benthic organisms to reproduce, but the positive is that you don't have nearly as much space for crud to accumulate. the decision is largely aesthetic.

two things i noticed in your code: as safety features, you should add in a debounce-like feature to your temperature actions. i.e., if your temp bounces over a set point for a millisecond, you dont want your lights/other devices cycling on and off. make it hold temp for 5-10 minutes before you take an action. along that same vein, if your temp probe freaks out and reads way above or below your temperature range, you should have it throw and error and ignore actions. specificially, if your temps show greater than 95 or less than 65, you know that those values arent reality and shouldnt result in a taken action.

well done!

+1 to woods on being very careful With which macros you put in your display with respect to your long term livestock goals.

Pm jeeperty.

into the sump, i would imagine, and the ability to get to overflows, arms in the tank, etc.

IIRC, Theresa's thread was for the whole shebang, tank included. I would put 5k at the high end, not the low end. Maybe 500-1,000 for electrical pull if they put in a dedicated circuit (which you probably should considering your livestock) and then 1-2k for the stand/cabinetry. It might be worth investing in a metal stand so that you can have the feet wide enough to get a sump in or out if you have to. Maybe another couple hundred to wire your lights through the arch to keep the look clean? The final piece to consider would be how you intend to control temps. If you're going to evap you should probably dump that wet sump air (either vented inside your house or forced outside outside the sump so it doesn't stay trapped in your cabinet and ruin your apex). If you intend to run a chiller then you're going to have to do some additional homework. Of course the devil will be in the details that no one is thinking of.

Were you running the evap fan in tandem with the chiller ?

How recently was that pH probe calbrated, and how old is the probe? I wouldn't worry about adjusting pH if the answers to those questions are a) not recently and b) old.

SKIMMERS, AMIRITE!!??!

that's a lot of water for a 29g biocube...

I'm looking forward to the airing of grievances.

Which would explain why the guy started it but never finished it.

Gotta be a typo, 250 lbs .

is there any way to rename the channels to mimic the a360?
